The ocean and canyon view
We were asked several years ago to consult on a “view” property in Malibu, California, that had been red-tagged (deemed unsafe for occupancy) due to earth movement and undermining of the house by a landslide that had occurred during the winter rains of 2004/2005. The client contacted us in May, 2015, after he purchased the property.… Continue Reading Red Tag Alert: View for Days Comes With a Price
Example of exterior wall cracking.
At Helfrich-Associates, we know how important it is to do your research when starting a new project. We were asked to investigate a property located in Los Angeles. The house we visited was originally constructed in 1937 and alterations were performed in 1957 and 2010-2011.… Continue Reading The Importance of Research
We were hired to evaluate the interior ceiling cracks in a home in Fullerton. CA. A contractor performed measured floor elevations to see if there was any foundation or slab movement and their measurements showed that the slab had not moved. So, foundation settlement was ruled out.
During our site inspection it was noted that the eaves were between 5 and 6 feet wide. A normal eave is between 2 and 3 feet wide. It was also noted that stucco had been added to be bottom of the eaves which made them heavier than normal eaves.
What do you do when the tree you love is causing damage to your building?
On one of our recent projects, we visited an apartment building complex where one unit had visible damage caused by tree roots. The adjacent unit had no damage.
However, upon further examination we discovered damage to the sidewalks, and it became obvious that tree roots are growing underneath the foundations. We observed a 23-feet-section of the exterior wall that has been lifted several inches.… Continue Reading Trees: A Thin Line Between Love & Hate
What happens when the fix for a problem creates another problem?
We were hired to investigate peeling drywall tape at a home in Hacienda Heights. A recent water loss occurred at this property and required a drying out process that used 6 dehumidifiers and 30 fans. The dehumidifiers and fans were running 24 hours a day for 29 days.
After the drying out process, the homeowner noticed that the drywall tape was peeling in their kitchen, living room, and two of the bedrooms.
The lesson from this project is pay close attention to what the repairs might involve; and try to anticipate possible side-effects to the repairs.
We were hired to investigate a property that had experienced tree root damage. Tree roots had cracked and lifted a concrete patio next to the house. The owners were concerned about possible damage to the structure.
The interior and exterior of the building showed minor foundation movement. However, no roots were discovered underneath the foundation of the building.
Do you know the common signs of home damage and deterioration? It’s important to be aware of changes around your home or property that could be signs of deterioration. These signs could be sagging beams, discoloration on ceilings/walls, cracks in floors & foundations, rust on steel stairs, tipping of retaining walls or slope movement.
Let’s face it, home or property repairs are never fun. They’re costly and time consuming. Most of us want to get them done as quickly and economically as possible. Yet there’s one thing you should never exclude from your project — a consultation with an experienced construction engineer about the signs of home damage.… Continue Reading Common Signs of Home Damage and Deterioration
Hearing your property has a termite infestation can send chills down any property owner’s spine. The cost of ridding a property of termites can be out of budget for many folks. Dealing with them is also inconvenient because most cases involve fumigation to make sure that you’ve rid a structure of the whole colony. It’s no wonder that many opt to put off the problem. That’s especially easy to do because it’s a problem that is often occurring out of sight – making it easy to put it out of mind.… Continue Reading Termite Damage and HOAs
Now that most of California has emerged from a severe drought, thanks mostly to a very robust 2016-17 rainy season, most Californians are feeling pretty optimistic about using more water.… Continue Reading Got that Sinking Feeling? Land Subsidence Due to Drought Conditions

Last week California’s Oroville Dam, the tallest dam in the United States, almost failed due to a surplus of water filling Lake Oroville. As the lake filled higher and higher, water was being released, via spillways, into the Feather River. The volume of water caused erosion of the dam’s main spillway, causing it to crater and break apart. As a result, the dam’s emergency spillway began to erode. That spillway had never been used and was unlined. The lack of concrete lining may have led to its erosion as well.
Nearly 200,000 people were evacuated from the area, many of them fleeing to higher ground cities like Sutter. As the water began to recede, residents began to travel back home.
But what went wrong? What caused the damage in the first place?… Continue Reading Oroville Dam Engineering: What Happened?
